## Methods

`public override Task<BuildStepResult> ExecuteAsync(ProcessDefinition processDefinition)` 

Adds timer-based transitions for activities whose [ActivityDefinition.IdleTimeout](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityDefinition/) uses [ActivityTimeoutType.SetActivity](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityTimeoutType/) or [ActivityTimeoutType.SetState](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityTimeoutType/).

### Returns

| Type | Description |
| --- | --- |
| `Task<BuildStepResult>` | A failed [BuildStepResult](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/BuildStepResult/) when an unknown [ActivityTimeoutType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityTimeoutType/) is encountered, or a successful result containing the updated process definition when processing completes. |
